| Identity & Market | ||
| Base polymer / chemistry | PLA filled with wood powder — 10–18 wt% (Bambu Lab SDS); colorFabb woodFill uses a PLA/PHA base with recycled wood fibre[1][2] | Thermoplastic polyurethane, polyester or polyether based, at about 92–95 Shore A[3][4] |
| Densityg/cm³ | 1.15 (colorFabb) to 1.23 (Fiberlogy), ISO 1183; Bambu Lab 1.21[5][2][6] | 1.20–1.25 (ISO 1183); Prusament 1.25, Polymaker 1.20–1.24, Bambu Lab 1.22[3][4][7] |
| Typical priceUSD/kg | 1 kg spools cluster near 25; counting the 0.5 kg specialty spools the middle of the market is about 34[8][9][10] | 1 kg spools cluster near 35; the specialist and industrial brands run to 106[11][12][7][13][14][15] |
| Price range across brandsUSD/kg | 14–76 across brands; SUNLU 14, ELEGOO 19, Bambu Lab 25, Prusament 44, Filament PM 49 on 0.5 kg spools, colorFabb 76[9][8][12][16][17][10] | 23–106 across brands; IEMAI 3D 23, LANDU 24, Siraya Tech 25, PS Imports 25, PrimaCreator 32, Bambu Lab 35–42, Polymaker 40–50, add:north 72, Recreus 90, 3DXTech 96, NinjaTek Cheetah 106[12][18][11][19][13][14][20][21][22][15] |
| Market availability1–5 | Stocked by most mainstream brands[8][9][16][6] | Ubiquitous, every brand and retailer[11][19][12][18][13][14] |
| Spool sizes & diameters | 1.75 and 2.85 mm; 0.6, 0.85 and 1 kg spools[16][6][8] | 1.75 and 2.85 mm; 0.5, 0.75 and 1 kg spools[11][19] |
| Typical applications | Decorative and model-making prints that are sanded and stained like timber[5][2] | Gaskets, phone cases, tyres, vibration mounts and protective covers[23] |
| Diameter tolerance± mm | ±0.03 (Bambu Lab)[5] | ±0.06 (Prusament) — the loosest tolerance Prusa publishes, because soft filament deforms in the gauge[4] |
| Printing Parameters | ||
| Nozzle temperature°C | 190–240 (Bambu Lab); colorFabb advises 195–220 for its PLA/PHA base[5][2] | 210–240; Polymaker 210–230, Prusament 230 ± 10, Bambu Lab HF 220–240[3][4][7] |
| Bed temperature°C | 35–45 (Bambu Lab); 50–70 (Fiberlogy)[5][6] | 25–65; Prusament 65 ± 10, Bambu Lab 30–35, Polymaker 25–60[4][7][3] |
| Enclosure / chamber requirement1–5 | Open frame is fine[5] | Open frame is fine[3] |
| Part cooling fan | Fan on[5] | Fan on[3][7] |
| Bed surface & adhesion aid | Not documented | PEI sheet or painter's tape; Polymaker warns TPU can over-stick and advises a glue stick as a release agent[24][23] |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | Not documented | 2.4 at Polymaker's 30–50 mm/s and 2.4 at Prusa's 30 mm/s cap on a 0.4 mm nozzle at 0.2 mm layer; Bambu Lab's high-flow grade lifts the cap to 200 mm/s (16 mm³/s)[3][4][7] |
| Warping tendency1–5 | None[5] | None[3] |
| Bed-adhesion difficulty1–5 | Not documented | Sticks to most surfaces[3] |
| Stringing / oozing tendency1–5 | Not documented | Moderate — retraction tuning needed; Polymaker specifies 3–6 mm retraction, well above the 1–3 mm used for rigid filaments[3] |
| Overall printing difficulty1–5 | Easy — minor profile tuning; pre-drying is required and the wood content chars if it sits hot[25][5] | Intermediate — dry filament and a tuned profile; the speed ceiling is the main constraint[3][4] |
| Extruder requirement | Nozzles below 0.4 mm are not compatible; Bambu Lab does not recommend the AMS lite[25] | Direct drive strongly preferred. BASF rates its 95A grade as running on both direct-drive and Bowden machines, but every maker caps speed at 15–50 mm/s unless the grade is specifically high-flow[26][3][4] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass acceptable; hardened steel for volume work — Bambu Lab's PLA compatibility table lists no hardened-nozzle requirement, but its nozzle guide names wood among the abrasive filaments hardened steel exists for[25][27] | Brass fine indefinitely[28] |
| Abrasiveness1–5 | Moderately abrasive — wood fill[25] | Non-abrasive[28] |
| Nozzle clog risk1–5 | Moderate — needs dry filament and a clean nozzle; wood particles char and block small nozzles[25] | Moderate — needs dry filament and a clean nozzle[29] |
| Heat-creep / jam sensitivity1–5 | Not documented | High — all-metal hotend and strong cooling needed; soft filament buckles in the cold zone if it slows[23] |
| Hotend requirement | Not documented | No special hot-end required, but a direct-drive extruder is (Simplify3D)[24] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | High — 1.25 % saturated at 25 °C / 55 % RH, the highest in the PLA family[5] | Low (0.1–0.3 %) by Prusa's measurement at 0.04 % in 7 days, but Polymaker measures 0.82 % equilibrium and groups TPU with the highly hygroscopic materials[4][3][29] |
| Equilibrium moisture content at ~50 % RH% | 1.25 saturated at 25 °C / 55 % RH (Bambu Lab)[5] | 0.82 equilibrium (Polymaker); 0.02 after 24 h and 0.04 after 7 days at 22 % RH (Prusa)[3][4] |
| Drying temperature & time | 55 °C for 8 h in a forced-air dryer; Bambu Lab lists pre-drying as required[5][25] | 70 °C for 8 h (Polymaker); 70 °C for 8 h or an 80–90 °C heatbed for 12 h (Bambu Lab)[3][7] |
| Symptoms when wet | Bambu Lab flags pre-drying and ventilation as specific requirements for this grade[25] | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[29] |
| Effect of moisture on strength | No dry-versus-conditioned figures are published. At 1.25 % saturated uptake the practical loss shows as poor layer adhesion, rough surface and weak layers[29][5] | Polymaker groups TPU with nylon, PVA and PETG as highly hygroscopic and says these often need to stay in a dryer while printing; no dry-versus-conditioned figures are published[29] |
| Storage requirement | Not documented | Sealed with desiccant; often kept in a dryer during the print[29] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 26 ± 5 (Bambu Lab) and 28.4 (colorFabb) printed XY, ISO 527; Fiberlogy quotes 35 at yield[5][2][6] | 41.4 ± 1.3 printed (Prusament, ISO 37); NinjaTek Cheetah 39 ultimate (ASTM D638)[4][30] |
| Young's modulusMPa | 2360 ± 190 (Bambu Lab) and 2479 (colorFabb) printed XY, ISO 527; Fiberlogy 2950[5][2][6] | Not documented |
| Elongation at break% | 4.5 (colorFabb) to 15.3 (Bambu Lab) printed XY, ISO 527; Fiberlogy 6.5[5][2][6] | 551 ± 24 printed (Polymaker, ISO 37); the filament itself stretches 7264 % before break (Prusa, ISO 527)[3][4] |
| Flexural strengthMPa | 55 ± 4 printed XY, ISO 178 (Bambu Lab)[5] | Not documented |
| Flexural modulusMPa | 2780 ± 120 printed XY, ISO 178 (Bambu Lab)[5] | Not documented |
| Charpy impact, notchedkJ/m² | 3.81 (colorFabb) and 6.3 ± 2.2 (Bambu Lab) printed XY, ISO 179, notched[5][2] | Not documented |
| Other impact data | Charpy unnotched 12.28 (colorFabb) and 15.7 (Bambu Lab), printed, ISO 179[5][2] | Not documented |
| Layer adhesion / Z tensileMPa | 15 ± 4 printed Z, ISO 527 (Bambu Lab); flexural Z falls to 28 against 55 in XY[5] | 9.5 ± 0.2 (Prusament interlayer adhesion, ISO 527)[4] |
| Brittleness1–5 | Brittle — snaps with little warning[5] | Very ductile — bends far before failing[3][4] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | 92 ± 0.4 Shore A and 39 ± 0.7 Shore D (Prusament); 95A (Polymaker, ISO 7619-1); 91 Shore A / 40 Shore D (Fiberlogy FiberFlex 40D, ISO 7619); 95A (NinjaTek Cheetah, ASTM D2240); 94.5 A measured on a printed Bambu Lab 95A part and 96.2 A on a Qidi one (My Tech Fun)[4][3][31][30][32] |
| Creep resistance / sustained load1–5 | Poor — no wood-filled creep test; plain printed PLA sagged from 12 to 16.2–21.8 mm over 5 days at 1.25 kg[33][34][35] | Poor — deforms under load at room temperature; a loaded bar crept from 74.5 to 82.7 mm over 5 days[32] |
| Fatigue / repeated-flex resistance1–5 | Poor — no grade-specific S-N curve; plain printed PLA ran 38 000–49 000 cycles at 30 % of tensile strength and the wood filler cuts elongation and the parts snap without warning[36][5] | Excellent — living hinges viable[23] |
| Elasticity / flexibility1–5 | Rigid[5] | Rubbery / highly elastic[3][4] |
| Z strength as % of XY% | 58 by tensile, 51 by flexural (printed, Bambu Lab)[5] | Not documented |
| Wear resistance & friction | Not documented | Abrasion resistance is a headline property; BASF measures 64 mm³ loss by ISO 4649 on its 92A grade[26] |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 60 (ISO 75, 0.45 MPa)[5] | Not documented |
| HDT at 1.8 MPa°C | 57 (ISO 75, 1.8 MPa)[5] | Not documented |
| Glass transition (Tg)°C | 54 (Bambu Lab, DSC); Fiberlogy quotes 55–60[5][6] | Not documented |
| Melting point / Vicat°C | 156 peak melt (DSC)[5] | 144 melting (BASF 95A, ISO 11357-3); Bambu Lab 183, Polymaker's modulus at 100 % elongation 8.9 MPa[26][7] |
| Continuous service temperature°C | Not documented | Bounded by a melting point of 144–183 °C; no loaded-bar service figure is published for TPU[26][7] |
| Flammability / UL 94 | Not documented | Flammable; no UL 94 rating published for the grades surveyed[3] |
| Environment & Chemical | ||
| UV resistance1–5 | Degrades within weeks outdoors[37] | Good — years with some colour shift; Polymaker lists UV exposure among the conditions TPU withstands[23] |
| Chemical resistance | Not documented | Good resistance to oils and common solvents (BASF)[26] |
| Food contact | Not documented | Not food safe without specific certification (Polymaker)[23] |
| Biodegradability / compostability | Not documented | Not biodegradable[23] |
| Recyclability | Not documented | Not accepted in household plastic collection[23] |
| Health & Safety | ||
| Fume toxicity1–5 | Low hazard — minimal VOC and particle emission[38] | Low hazard — minimal VOC and particle emission; TPU was not among the nine filaments in the chamber study[38] |
| Ventilation / filtration requirement1–5 | None needed in a normal room; Bambu Lab specifically advises ventilation for this grade[25] | Open a window / occasional ventilation[38] |
| Post-Processing | ||
| Sanding & machining | Sands and stains like timber — the usual reason for choosing it[2] | Sanding is impractical — the surface tears rather than abrades[23] |
| Gluing & solvent welding | Not documented | Cyanoacrylate bonds TPU; no common solvent welds it[23] |
| Vapour / chemical smoothing | Not documented | No practical vapour smoothing[23] |
| Support material pairing | Support for PLA (Bambu Lab)[5] | Polymaker warns TPU supports are often very difficult to remove; PolyDissolve S1 is rated for TPU[23] |
| Dimensional accuracy & detail | Wood grain hides layer lines; colour darkens with nozzle temperature[5][2] | Stringing and elephant-foot are the accuracy limits; retraction has to be long and slow[3] |
| Solvents & Solubility | ||
| Soluble in | Chloroform dissolves the PLA matrix (10 % w/v, 2–4 h at 23 °C) and leaves the filler as loose sludge; laboratory reagent.[39] | DMF, DMSO, NMP and THF dissolve TPU; acetone, MEK and cyclohexanone are partial solvents. All laboratory reagents.[40] |
| Softened or crazed by | Acetone, ethyl acetate and toluene plasticise the matrix but dissolve <1 % even at 65 °C; acetone submersion crazes parts.[39][41] | Toluene and benzene swell it up to +50 % by weight at 23 °C; esters swell it severely; ethanol and IPA soften it.[40] |
| Solvent welding & smoothing agent | Chloroform vapour attacks only the resin fraction, so the filler is left standing proud; no workshop-safe agent exists.[42][41] | None practical — the true solvents (DMF, THF, NMP) are laboratory reagents and leave the joint swollen and weak.[40] |
